The Neoproterozoic Cryogenian Datangpo manganese of the Nanhua Basin that was formed after Cryogenian Sturtian glaciation has been one of the major manganese production sites,the mineralization backgrounds and development mechanism of which have received much more attention.The initiation and termination ages of the Sturtian glaciation and the mineralization ages of the Datangpo manganese deposits,the architectural evolution of the Nanhua Basin,the weathering intensity and climatic conditions,and the formation mechanism of the Cryogenian manganese deposits were reviewed.Methods:This paper systematically summarized the commence and termination ages of the Sturtian glaciation elsewhere around the world,the tectonic architecture of the Nanhua Basin and the paleoclimate evolution during the deglaciation of the Neoproterozoic Cryogenian;meanwhile.the causal relationship between the metallogenesis of depositional manganese deposits of the Nanhua Basin and the aforementioned major geological events were comprehensively documented.Results: The Sturtian glaciation of the Nanhua Basin initiated at ~ 717 Ma and terminated before ~ 660 Ma.The syndepositional fault-controlled horst and graben subbasins were formed in the interior of the Nanhua Rift Basin.The weathering indices such as chemical index of alteration (CIA),Li isotope (δ7Li) and Os isotopic composition (187Os/188Os) are indicative of a cold and arid climate of the Nanhua Basin during the late Sturtian glaciation to early interglacial Datangpo Age.The climatic condition changed into a warm and humid climate,quickly returned into a cold and arid climate until the middle to late Datangpo Age,and then transited into a warm and humid climate that persisted into late Datangpo Age.The surface seawater of the Nanhua Basin was well oxygenated after the Sturtian glaciation; meanwhile,the deep water was dominated by anoxia with intermittently oxic condition.Conclusions: The initiation and termination of the Sturtian glaciation of the Nanhua Basin took place most likely synchronously with elsewhere around the world.The mineralization timing of the Cryogenian Datangpo manganese deposits likely developed before ~ 660 Ma.The hydrothermal fluids provided considerable amounts of metallogenesis materials for the Datangpo manganese deposits and dictated their developments,which were precipitated, and were accompanied by organic matter burial and microbe- mediated to transferred into rhodochrosite during early diagenesis.
